The polynomial equation has a solution which is not an integer, but it is a rational number. To use your calculator to help you find the solutions in such a case, set the xscl to 1/3. (Why would we do this?) Set the window to: Xmin = -5 Ymin = -20 Xmax = 5 Ymax = 60 Xscl = 1/3 Yscl = 1

The characteristic polynomial is defined as: The roots of = 0 will give the necessary information about the stationarity or nonstationarity of the process. The necessary and sufficient condition for stability is that all characteristic roots lie outside the unit circle. Then is of full rank and all variables are stationary.

Rational Root Theorem - In the polynomial, an xn + an-1 xn-1 + · · · + a1 x + a0 = 0 where the coefficients an ,an-1 , . . . ,a1,a0 are integers. If a rational number c/d, is factored to its lowest terms, is a solution to the equation, then c is a factor of the constant term of the polynomial and d is a factor of the leading coefficient of ...

The Rational Root Theorem states that any rational solutions to a polynomial will be in the form of where p is a factor of the constant term of the polynomial (the term that does not show a variable) and q is a factor of the leading coefficient. This is actually much simpler than it appears at first glance. Let us consider the polynomial

The constant coefficient is the negative product of the roots for a cubic. In general, this coefficient is either the positive or negative of the product of the roots for any polynomial. The sign depends on the degree of the polynomial – if it's even, the sum is the positive one, otherwise it's negative.
